Head brownish, ratlier elongated, rostrum brown, also some- 

 what prolonged ; palpi and antennae brownish ; second joint of 

 the latter stout ; thorax reddish-yellow above, with three indis- 

 tinct brownish stripes, the intermediate one with a faint yellow 

 line in the middle. Pleurai with a brown line, bordered with
